Diffuser body is 4 in” (10 cm) longer than OEM diffuser. Fins sit 5 in” (12.7 cm) off the ground on stock suspension. Fins run parallel to the ground and extend forward to the undertray to channel air properly out the rear of the car. This reduces drag and improves downforce. Fins are squared off to keep air channeled in between the fins longer, preventing air spill. This diffuser was put to the test by professional Lotus Cup Series racers and autocrossers nationwide.
